Publication number: 20210052400Abstract: A prosthetic attachment system includes an insert arranged for connection to a prosthetic liner, and an attachment unit arranged for connection to a distal end of a prosthetic socket. The attachment unit comprises a body defining an axis and a central opening for selectively receiving the insert. The body carries a plurality of locking elements that are distributed circumferentially about the axis and radially repositionable relative to the axis. A release mechanism is slidably positioned on an outer surface of the body to move the prosthetic attachment system between a locked configuration in which the locking elements are radially repositioned to lock the insert in the central opening of the body and an unlocked configuration in which the insert is released from the central opening.Type: ApplicationFiled: November 9, 2020Publication date: February 25, 2021Inventors: Dadi GRANZ, Martin Lund STORUP, Andrew BACHE, Linda Ros BIRGISDOTTIR, Egill Sveinbjorn EGILSSON, Lukas KALEMBA, Eelco DOLFSMA

Patent number: 10918503Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.Type: GrantFiled: April 18, 2018Date of Patent: February 16, 2021Assignee: OSSUR ICELAND EHFInventors: Andrew Bache, Egill Sveinbjorn Egilsson, Linda Ros Birgisdottir, Dana Stewart Marlin

Patent number: 10898352Abstract: A suspension liner is adapted to provide an interface between a residual limb and a prosthetic socket. The suspension liner defines an interior surface and an exterior surface forming a liner profile between a closed distal end and an open proximal end. The suspension liner defines a liner body portion formed from an elastomeric material and at least one seal protruding circumferentially about and radially outward a distance from the liner profile, which is defined at areas outside the at least one seal. The at least one seal has a distal root extending from the liner profile, a distal section projecting from the distal root and terminating at a peak defined as the outermost portion of the at least one seal, and a proximal section extending from the peak to a proximal free end arranged for deflection relative to the liner profile.Type: GrantFiled: March 14, 2018Date of Patent: January 26, 2021Assignee: OSSUR HFInventors: Egill Sveinbjorn Egilsson, Sigurdur Asgeirsson
